- LUeRicAToa] SPECIFICATION forming part of. Letters Patent No. 270,762,dated January 16, 1883.

Application filed August 19, 1882. (No model.)

v To all whom it may concern Be it known that I, LEVI P. DoLusolN, ofWabash, in the county of Wabash and State of Indiana, have invented anew and Improved Lubricato'r, of which the following is a full, clear,and exact description.

The object of my invention is to facilitate the lubricating of thecommutators of dynamoelectric machines to prevent the brushes fromcutting into the commutators.

The invention consists ina rocking frame provided with rollers to whichbands saturated with oil are attached and with rollers over which thebands pass, one of which rollers, to which the bands are attached, beingprovided with a ratchet-wheel with which a fixed pawlspring engages,thereby rotating the said roller when the frame rocks, and thus Windingthe bands from one roller to the other, so that a fresh surface of thebands will come in contact with the object to be lubricated every timethe frame rocks. The frame is rocked by an eccentric wheel operated fromthe shaft carrying the object to be lubricated, as will bev more fullydescribed hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

- longer end of the said frame will be above the lower ends by a roller,G, and by a roller, H,

a short distance inside of the roller Gr. The

side bars are also connected by a roller or reel, J, between the rollersH and F. The side pieces of the frame A are provided withdownwardly-projecting arms K, in the ends of which a roller, L, isjournaled, on which a ratchet- N, attached to a cross-piece, O,connectingthe standards A, has its free end resting on the ratchet-wheelM. Bands P, of felt, cotton, or other suitable material, are wound onthe reel J, pass around the end roller, G, over the roller H, and arethen attached to the roller L. The end of the shaft 0 on which thecommutators C are mounted is provided with a worm-thread, Q, engagingwith a worm-wheel, R, mounted on an inclined shaft, S, provided at itsupper end with a worm-thread, T, engaging with a worm-wheel, U, mountedon one end of a transverse shaft, V, journaled in the upper ends of thestandards A, on which shaft V an eccentric wheel, W, is mounted. Theinclined shaft S is journaled in projections of the brush-holder and oneof the standards.

The operation is as follows: The bands or ribbons P are soaked in oil,and-are thenwrung out and wound on the reel J and fastened to the reelor roller L, as described. The rotatting shaftC rotates the shaft S,which'in turn rotates the shaft V on which the eccentric wheel W ismounted. As the eccentric disk or wheel U rotates it alternatelydepresses and releases the upperend of the frame A. When the upper endof the frame Ais depressed thelower end will be raised from theeommutators, and

lubricating material in the bands P. Every time the shaft V rotates thebands P will be brought in. contact with the commutator, and by changingand adjusting the gearing the number of contacts within a given time canbeiucreased or decreased. The frameAswings on the shaft F, and everytime the frame A swings upward the roller L swings forwardthat is, fromthe cross-piece O-and the ratchetwheel M slides under the free end ofthe spring N; and when the frameA swingsdown the roller L swings towardthe cross-piece 0. The teeth of the ratchet-wheel M catch on the end ofthe spring N. The wheel M will be rotated in V the direction ot' thearrow to, and thereby the roller L will be rotated, and part of thebands Pwill be wound on the roller L. A part of the band is wound on theroller L every time the frame A rocks, so that a fresh surface or partof the bands will come in contact with the commutators every time theframe A swings. As many bands I? can be mounted in the frame A as thereare commutators on the shaft 0'.

Having thus described my invention,I claim as new and desire to secureby LettersPate'nt 1. A lubricator made substantially as herein shown anddescribed, and consisting of a swinging frame containing bands orribbons saturated with oil or other lubricating material, which bandsare repeatedly brought in contact with the surfaces to be lubricated, asset forth. n

2. In a lubricator, the conibination,with a rocking frame, of bandswound on rollers of the said frame, and of devices for graduallytransferring the bands from one rollerto the other by the movements ofthe rocking frame, substantially as herein shown anddescribed, and forthe purpose set forth.

3. In a lubricator,,the combination, with a rocking frame, of bandsattached to the rollers in the said frame, and of a ratchet-wheel andpawl-spring for winding the bands from one roller to the other by therocking motion of the frame, substantially as herein shown anddescribed, and for the purpose set forth.

4. In a lubricator, the combination, with a rocking frame, of oiled orprepared bands on rollers in the said frame, and of devices for rockingthe said frame from the shaft on which the objects to belubricated aremounted, substantially as herein shown and described, and for thepurpose set forth.

5. In a lubricator, the combination, with the standards A of the rockingframe A, provided with rollers over which bands I are passed, therollers J and L, to which the bands P are attached, the ratchet-wheel Mon the roller L,

and the spring N on a cross-piece of the worm-wheel II on the end of theshaft V, the

shaft S, provided with a worm-thread, T, at its upper end, theworm-wheel B, mounted on the shaft S,and the shaft 0 ofthe machine,which shaft is provided with a wornrthread, Q, engaging with theworm-wheel R, substantially as herein shown and described, and for thepurpose set forth.
